A tunable stay device for an aircraft closure has a mounting base that is mountable to the closure or in an area of the aircraft in close proximity to the closure. The mounting base extends, at least in part, along a mounting axis. A holding element is mounted for movement along the mounting axis and configured to effect, at least in part, a hold force. An adjuster is mounted to at least one of the mounting base and the holding element and is configured and arranged to effect a change in position of the holding element with respect to the mounting base along the mounting axis. When the stay device is mounted to the closure or in the area of the aircraft in proximity to the closure, the hold force biases the closure in one of an open orientation and a closed orientation.
